Aside from wanting a 25p option (as I live in a country with 50 Hz power supply) that would be fine for my non-professional videography needs.

I know Oly's focus has always been on stills, but what PRO camera in 2013 has such limited and pathetic video quality options?

They all offer Full HD at 30 / 25 / 24 p. Whether the video is much good is a worthwhile consideration, however. The E-M5 has very limited video capability but the IBIS is better than anything available elsewhere.

As usual, you have to consider the overall picture (moving, in this case) and decide what suitable trade-offs are.

To reiterate: in my view, this is not intended to be a 'PRO' video camera.

This is going to hurt sales. no doubt. What a mistake.

I doubt it will have much effect on sales.

If Olympus wanted to fight over videographers then that's a fairly difficult market and the costs of implementing a very high standard of video (assuming that the sensor in the E-M1 can support it) would be high.

The market they are targeting is high end still photographers who will want to use high end lenses such as the new "PRO" line or the standard FT HG and SHG lenses.
